Singapore is the "model compact city", says architect Khoo Peng Beng, and city planners who have to prepare for an ever-growing number in limited areas should learn a lesson from the model city.
Khoo, lead curator of Singapore's pavilion at the Venice architectural Biennale, opens his argument with some startling figures to demonstrate the compactness of the tiny island state off the Malaysian peninsula.
It is planning for a maximum population of 6.5 million in 20 years, which is 1,000th of the current world total of 6.5 billion.
Yet 1,000 times the land area of Singapore would occupy only 0.5 percent of the total world land mass, equivalent to about twice the size of Italy, Khoo said.
Maps at the exhibit shrink China and the United States to the tiny spaces they would occupy if they had the same density as Singapore, which has a land area of just 710 square kilometres (275 square miles).
The exhibition titled "1,000 Singapores: A Model of a Compact City" stresses the advantages of compactness such as minimising energy consumption, streamlining transportation and reducing the carbon footprint.
"Architecture, social systems, transport systems, waste management and so on are working hand in hand in a meta-project," Khoo told AFP, describing Singapore's evolution as a "very slow process of self-invention, as an island, a country, a city."
One of the world's richest cities and widely acclaimed as among the most "liveable", Singapore has avoided the congested feeling of places like Hong Kong and Tokyo until recent years.
